iOS 18.4.1—Apple Issues New Update Warning To All iPhone Users
Apple has released iOS 18.4.1 and it comes with a warning to update your iPhone now. That's because iOS 18.4.1 fixes two iPhone security flaws, both of which are being used in real-life attacks.
Apple doesn't provide a lot of detail about what's fixed in iOS 18.4.1, because the iPhone maker wants to give people as much time to update before more attackers can get hold of the details.
The first flaw fixed in iOS 18.4.1 is an issue in the iPhone's CoreAudio tracked as CVE-2025-31200 and reported by Apple and the Google Threat Analysis Group. Processing an audio stream in a maliciously crafted media file may result in code execution, Apple warned on its support page.
'Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS,' the iPhone maker added.
The second bug patched in iOS 18.4.1 is a flaw in RPAC tracked as CVE-2025-31201 and reported Apple. The vulnerability could allow an attacker with arbitrary read and write capability to bypass Pointer Authentication, Apple said, adding that the issue may also have been exploited in an 'extremely sophisticated attack.'
The iOS 18.4.1 update comes just two weeks after the release of iOS 18.4, which itself patched 62 vulnerabilities, highlighting the importance of the latest upgrade.
In March, Apple again addressed an already-exploited flaw in the iOS 18.3.2 update.
Apple's iOS 18.4.1 is an emergency security update that comes in between major point upgrades, ahead of iOS 18.5's arrival in May. There is no iOS 17 update for older iPhones, perhaps because the operating system is not affected by this flaw. However, Apple is no longer issuing security updates to iOS 17 users that are able to upgrade to iOS 18.
Despite the urgency of the iOS 18.4.1 upgrade, there is no need to panic, because as Apple said, the flaws fixed in iOS 18.4.1 were used in targeted attacks. These are likely against journalists, dissidents, government officials and businesses in certain sectors. Yet if attackers get hold of the details, they can use the flaws more widely.
Apple's iOS 18.4.1 also addresses several bugs, including one that prevents wireless CarPlay connection in certain vehicles.
The iOS 18.4.1 update is available for the iPhone XS and later, iPad Pro 13-inch, iPad Pro 13.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later.
So what are you waiting for? Go to your iPhone Settings > General > Software Update and download and install iOS 18.4.1 now.

iPhone 17 Pro could get unexpectedly huge camera upgrades
Over the past few months, leaks showing a redesigned iPhone 17 Pro pair and an uber-slim iPhone 17 Air have occupied social media. But it seems the upcoming Apple flagships will serve a few other niceties that will appeal to camera fans. According to a Macrumors report, which cites an unnamed source, the iPhone 17 Pro will come with an upgraded 8x optical zoom camera. For comparison, the iPhone 16 Pro pair is limited to 5x optical zoom output. Apple is stepping up Looking over at the competition, Samsung's Galaxy S25 Ultra and Google Pixel 9 Pro peak at 5x optical zoom output. Stepping into the hypercompetitive Asian markets, Oppo's Find X8 Ultra goes up to 6x optical zoom, and the Huawei Pura 80 Ultra reaches the 9.4x optical zoom figure. 'The lens can apparently move, allowing for continuous optical zoom at various focal lengths,' adds the report. To recall, all the leaks point at a massive camera bump at the back of the iPhone 17 Pro, so it's plausible that Apple is indeed eyeing a major upgrade for the imaging hardware. Recommended Videos Assuming the rumor turns out to be true, the iPhone 17 Pro will emerge as one of the best smartphones out there for long-range photo and video capture, at least going by the on-paper hardware. Whether Apple upgrades the tetraprism design for the next-gen telephoto camera system remains a mystery. A true camera powerhouse, at last Older leaks are also predicting a triple 48-megapixel camera layout for the iPhone 17 Pro, with support for 8K video capture in tow. We are also hearing some chatter about a mechanical aperture feature that will offer users more granular control over photo capture. The camera app will reportedly allow simultaneous capture by the front and rear snappers, a solution that is tailor-made for vlogging. This facility, however, isn't exactly a groundbreaking innovation, as the likes of Samsung have offered it for years on the Galaxy smartphones. The latest Apple leak also claims that Apple will release a new camera app with the iPhone 17 Pro, one that will focus on Pro-grade features and deeper controls. So far, the likes of Halide and Kino have remained a favorite in the 'mobigrapher' community, so it would be interesting to see what Apple has to offer in terms of standout capabilities.
